Vlink
Introduction
Vlinks is a Sanet's subapplication that makes it possible to create "virtual" links between any pair of interfaces.
This subapplication requires additional database data and it's not enabled by default.
Differences with normal links
A vlink has no restrictions about what couple of interfaces it links together.
- You can link the same couple of interfaces several times.
- You can link an already-linked interface with any other interface.

Web Maps
Inside web maps, vlinks are rendered as like as the real links. The state of the link (the color of the link) depends on linked interfaces' status.
Installation
Add the application "vlink" the the list of INSTALLED_APPS.
Example: add the following lines to your $SANET_HOME/settings.py
if not 'vlink' in INSTALLED_APPS:
INSTALLED_APPS.append('vlink')
And update the database schema:
python manage.py syncdb
Configuration
CLI commands
To add a virtual link between two interfaces use the command
vlink <node1> <iface1> <node2> <iface2>
To remove a vlink:
no vlink <node1> <iface1> <node2> <iface2>
